- High availability and failover
  You can configure clustered HCL Launch servers, and agents for high availability. You can also configure agents and agent relays for failover.
- Setting up high-availability clusters
  To configure a high-availability cluster, you store shared files on network storage. Then, you configure multiple servers, set each server to access the same files and database, and configure a load balancer to distribute the traffic between the servers.
  - Setting up clusters of servers
    To configure a cluster of servers, set up a shared database and file system for the servers to use.
  - Adding servers to clusters
    You can add new servers to a cluster at installation time, or you can move existing servers to be part of a cluster.
  - Converting a stand-alone server to high availability
    You can convert an HCL Launch server into the first node of a high-availability cluster.
- Adding cold standby servers
  You can add cold standby servers to serve as a backup server or for disaster recovery. You must start the secondary server or servers when the active server fails, and network traffic is routed to the secondary servers.
- Backup and recover
  You can back up and recover the contents of your HCL Launch installation.
- Server settings and configuration
  After you install HCL Launch, you can modify the server configuration and configure more options.
- Setting user preferences
  Each user can specify display options for the server, including the language for the server and how the server shows times and dates.
- Agents and agent relay configuration
  After you install an agent for HCL Launch, you can modify its configuration or create an agent relay to facilitate communication to remote relays.

Setting up high-availability clusters

To configure a high-availability cluster, you store shared files on network storage. Then, you configure multiple servers, set each server to access the same files and database, and configure a load balancer to distribute the traffic between the servers.

About this task

The specific steps depend on whether you are clustering servers or engines.
